<!-- EDIT TEMPLATE DOCUMENTATION BELOW THIS LINE -->

De '''Citation''' sjabloon genereert een bronvermelding voor een boek, periodiek, tijdschrift, krant of website. Op basis van de gebruikte parameters bepaalt de sjabloon om welk soort bronvermelding het gaat.

De sjabloon dient na de interpunktie, zoals een punt of komma, ingevoegd te worden.

==Simple citation==
This template gives the most commonly used attributes. You can copy the horizontal form or vertical form below and then add in extra attributes from the full list. Spacing and ordering is irrelevant.

<code><nowiki>{{Citation | last = | first = | year = | title = | publisher = | publication-place = | page = | url = | accessdate = }}</nowiki></code>

* '''last''': The author's surname or last name. Don't use with '''author'''.
* '''first''': The author's first or given name(s).
* '''year''': Year of authorship or publication. Mandatory for use with links from [[:Template:Harvard citation]], unless {{para|date}} specifies both month and year.
* '''title''': Title of the work. Mandatory for web references.
* '''publisher''': The name of the publisher. Omit terms such as ''Publishers'', ''Co.'', ''Inc.'', ''Ltd.'', etc., but retain the words ''Books'' or ''Press''.
** '''publication-place''' (or '''place'''): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office.
* '''page''': For use when one page is cited. Adds "p." before the page number. Do not use with '''pages'''.
* '''url''': An [[Uniform resource locator|url]] of an online location where the item can be found. If the url includes double quotes, these must be encoded as "%22".
** '''accessdate''': Date<ref group = "n" name = "dates" /> when the url was accessed.

* '''author''' (or '''author1'''): The author's name. It is preferable to use the last/first attributes below for single or multiple authors.
** '''last''' (or '''last1'''): The author's surname or last name.
** '''first''' (or '''first1'''): The author's first or given name(s).
** '''author2''', '''last2''', '''first2''', up to '''author9''' ''etc.'': can be used for multiple authors– up to 8 will be shown before ''et al.'' is displayed
** '''author-link''': Title of an existing Wikipedia article about the first author (author2-link ''etc'' can also be used).
** '''author-separator''': override the default semi-colon that separates authors.
** '''author-name-separator''': override the default comma that separates authors' last and first names.
** '''author-mask''': See [[#Additional parameters]], below.
** '''display-authors''': Truncate the list of authors at an arbitrary point with "''et al''". You should still include the first 9 authors to allow metadata to be generated. n.b. operates only when the authors are given using either several {{para|author''n''}}, or several {{para|last''n''}}{{para|first''n''}} pairs; does not affect the display of a list in either {{para|authors}} or {{para|coauthors}}.
** '''lastauthoramp''': If supplied, whether or not assigned a value, places an ampersand (&amp;) before the last name of final author, if more than one author is supplied. Recommended usage is ''lastauthoramp = yes''.
** '''coauthors''': Names of additional author(s) can be given but ''author2'' or ''last2'', ''first2'' is preferred.
* '''editor''': Name of editor, placed after date with <code>,ed.</code> Not required for periodicals.
** '''editor-link''': link to article about the editor
* '''others''': Any other associated people, ''e.g.'', foreword, placed after editor.
* '''publication-date''' (or '''date'''): Date<ref group = "n" name = "dates" /> of publication.
** '''date''': Date<ref group = "n" name = "dates" /> of authorship, if different from date of publication. If only ''date'' is used, it will be treated as the date of publication.
** '''year''': Year of authorship or publication. (Mandatory for use with links from [[:Template:Harvard citation]]. In some situations, the template may be able to derive a year from the full ''date''.)
*** '''month''': Month of publication (ignored if the ''date'' field is used).
** '''origyear''': Year of first publication, if different.
* '''title''': Title of the book or article in a periodical. If the title includes [square brackets], these must be encoded as "<code>&amp;#91;</code>" for "[" and "<code>&amp;#93;</code>" for "]"
* '''chapter''' or '''contribution''': title of the chapter or part of a publication will be put in quotes.
** '''chapter-url''' or '''contribution-url''': use to add a link to the chapter or contribution title.
* '''type''': An optional field which can be used to provide additional information about a publication type. The content appears in parentheses following the title. If the publication is a thesis or dissertation, the type might be specified as <code>type = PhD thesis</code>, If the publication is an audiobook on compact disk, the type might be specified as <code>type = CD</code>.
** '''journal''' or '''periodical''' or '''newspaper''' or '''magazine''' or '''work''': Name of the journal or periodical.
* '''edition''': Number or name of the edition, if not the first; for example: ''edition'' = 2nd.
** '''series''': The book series of which this book is a part.
** '''volume''': The volume number of a multi-volume book.
** '''issue''': Issue number of a periodical.
* '''publisher''': The name of the publisher. Omit terms such as ''Publishers'', ''Co.'', ''Inc.'', ''Ltd.'', etc., but retain the words ''Books'' or ''Press''. Not needed if ''ISSN'' or ''DOI'' used.
** '''publication-place''' (or '''place'''): The city of publication. If more than one town/city is listed on the title page, give the first one or the location of the publisher's head office. If the city is not well-known, you may add a county, region, or state. States in the U.S. are denoted by a two-letter code; for example: <code>place = Paris, TX</code> (no period at the end). Where the publisher is a university and the place or location is included in the name of the university, do not use this parameter.
*** '''place''' or '''location''': City in which the work was made, if different from the city of publication. If only ''place'' is used, it will be treated as the city of publication.
* '''language''': If not English. ''e.g.'', ''Finnish''.
* '''page''': For use when one page is cited. Adds "p." before the page number. Do not use with '''pages'''.
** '''pages''': For use when multiple pages are cited. Adds "pp." before the page numbers. Do not use with '''page'''.
** '''nopp''': if set to any value, <code>page = /pages = </code> do not generate 'p.' or 'pp.'. E.g. <code>nopp = true</code>. Using <code>at = </code> has the same effect.
** '''at''': Position within the resource when {{para|page}}/{{para|pages}} is inappropriate or insufficient. This parameter is ignored if {{para|page}}/{{para|pages}} is specified. Examples of usage of {{para|at}}: {{para|at|para. 14}} (when citing a source without page numbers), {{para|at|02:56}} (a film or audio timestamp), {{para|at|no. 456}} (something in a numbered list), {{para|at|p. 6, col. 2}} (for a page and a column because "column" is not a Citation template parameter), or {{para|at|sec. F pp. 4–6}} (for a section and a page within the section, "section" not being a parameter).
{{csdoc|id1}}
{{csdoc|id2}}
{{csdoc|url}}
* '''separator''': specifies the punctuation mark used to separate certain fields. This defaults to a comma; the [[Help:Citation Style 1|Citation Style 1]] family of templates uses a period.
* '''laysummary''': url of a lay summary of a technical article, which could be in a popular science magazine or newspaper.
** '''laysource''': Name of the source, ''e.g.'', ''The Guardian'' (UK newspaper) or ''New Scientist''.
** '''laydate''': The date<ref group = "n" name = "dates" /> of publication or, where this is not available, date of retrieval of the lay summary.
* '''postscript''': Set terminal punctuation. Omit or leave blank to remove the trailing full stop. Punctuation specified by this parameter will appear within the cite span, and consequently before any icons added by metadata-using software, ''e.g.'', library browser plugins. Hence this parameter should be used instead of manually appending data to the citation. This parameter is ignored if {{para|quote}} is specified, when {{para|postscript|.}} is forced.
* '''ref''': An explicit ID for Harvard references; see [[#Anchors for Harvard referencing templates|Anchors for Harvard references]]

==Anchored citations==
This template can generate a citation that can be combined with [[WP:CITESHORT|shortened footnotes]] or [[Wikipedia:Parenthetical referencing|parenthetical referencing]]. It does this by creating an [[HTML element#Anchor|HTML anchor]] containing an ID. The special parameter {{para|ref|harv}} generates an ID suitable for [[Harvard referencing]] templates such as {{tl|harv}} as specified in the next section; this is the default for the {{tl|citation}} template. If an empty {{para|ref}} is given, no anchor is generated; this is the default for the Cite templates such as {{tl|cite book}} and {{tl|cite news}}. You can also specify the ID directly, using the {{para|ref|<var>ID</var>}} parameter. For example, suppose an article's ''References'' section contains the markup:
* <code><nowiki>{{Citation | author = Sigmund Freud | title=Civilization and Its Discontents | year = 1930 | ref = CivDis}}</nowiki></code>
which generates the citation:
* {{Citation | author = Sigmund Freud | title = Civilization and Its Discontents | year = 1930 | ref = CivDis}}
Then, the markup "<code><nowiki>([[#CivDis|Freud 1930]])</nowiki></code>" generates a parenthetical reference "([[#CivDis|Freud 1930]])" containing a wikilink to the citation (try clicking on the wikilink).

===Anchors for Harvard referencing templates===
IDs compatible with Harvard referencing templates such as {{tl|harv}} are computed from the last names of the authors and the year of the cited source. For example, the markup "<code><nowiki>{{harv|Wright|Evans|1851|p = ix}}</nowiki></code>" generates the Harvard reference "{{harv|Wright|Evans|1851|p = ix}}", which wikilinks to the citation whose markup and appearance are shown below:
* <code><nowiki>{{Citation | last1 = Wright | first1 = Thomas | last2 = Evans | first2 = R.H. | title = Historical and Descriptive Account of the Caricatures of James Gillray | location = London | publisher = Henry G. Bohn | year = 1851 | oclc = 59510372 }}</nowiki></code>
* {{Citation | last1 = Wright | first1 = Thomas | last2 = Evans | first2 = R.H. | title = Historical and Descriptive Account of the Caricatures of James Gillray | location = London | publisher = Henry G. Bohn | year = 1851 | oclc = 59510372 }}
In this example the {{tl|citation}} template defines, and the {{tl|harv}} template uses, the HTML ID "<code>CITEREFWrightEvans1851</code>", composed by concatenating the string "<code>CITEREF</code>" with the last names of the authors and the year. The {{tl|harvid}} template can be used to generate such IDs, for example, <code><nowiki>{{harvid|Wright|Evans|1851}}</nowiki></code> generates "<code>{{harvid|Wright|Evans|1851}}</code>".

Related methods which leave only a number in the text are to use the {{tl|harvnb}} template enclosed in the <nowiki><ref></ref></nowiki> html code, or to use the {{tl|sfn}} template alone. The example above would be <code><nowiki><ref>{{harvnb|Wright|Evans|1851|p = ix}}</ref></nowiki></code> or <code><nowiki>{{sfn|Wright|Evans|1851|p = ix}}</nowiki></code> both of which generate a footnote, such as
:17. {{harvnb|Wright|Evans|1851|p = ix}}

The names of only the first four authors are used; other author names are not concatenated to the ID. If no author names are given, editor names are used instead. If these names are not given, this template does not generate an anchor.

Last names are used, as specified by the parameters {{para|last1}} (or {{para|last}}), {{para|last2}}, {{para|last3}}, and {{para|last4}}, and similarly for {{para|editor1-last}} etc. and for {{para|inventor1-last}} etc. If a full name is given but no last name is specified, this template falls back on the full name, but this usage is not recommended. For example, in "<code><nowiki>{{Citation | author = Sigmund Freud | title = The Ego and the Id | year = 1923}}</nowiki></code>" no last name is given, so this citation cannot be combined with the Harvard reference "<code><nowiki>{{harv|Freud|1923}}</nowiki></code>". To make these {{tl|citation}} and {{tl|harv}} invocations compatible, either replace "{{para|author|Sigmund Freud}}" with "{{para|first|Sigmund}} {{para|last|Freud}}", or add "{{para|ref|<nowiki>{{harvid|Freud|1923}}</nowiki>}}" to the {{tl|citation}} invocation, or add the same ref parameter (say, "{{para|ref|EgoId}}") to both the {{tl|citation}} and the {{tl|harv}} invocations.

Similarly, the year is used, as specified by {{para|year}}. If no year is given, this template attempts to derive the year from {{para|date}} (or, if no date is given, from {{para|publication-date}}) by applying the [[mw:Help:Extension:ParserFunctions##time|MediaWiki#time function]]. This heuristic works with many common date formats (American, International and ISO standard format YYYY-MM-DD as listed in [[WP:MOS]]), but may not work as expected with other formats, so when in doubt it may be safer to use {{para|year}}. Note that if only a year, say 2005, is known you must use {{para|year|2005}} rather than {{para|date|2005}}.

===IDs must be unique===
Names, years, and hand-specified IDs must be chosen so that the IDs are unique within a page; otherwise the HTML will not conform to the W3C standards, and any references to the citations will not work reliably. For example, suppose a page contains the following two citations with {{tl|harv}}-compatible IDs:
* {{Citation | last1 = Montes | first1 = G | last2 = Halterman | first2 = JS | year = 2008a | journal = Pediatrics | volume = 121 | issue = 4 | pages = e821–6 | title = Association of childhood autism spectrum disorders and loss of family income | doi = 10.1542/peds.2007-1594 | pmid = 18381511 | url = http://pediatrics.aappublications.org/cgi/content/full/121/4/e821 }}
* {{Citation | last1 = Montes | first1 = G | last2 = Halterman | first2 = JS | year = 2008b | journal = Pediatrics | volume = 122 | issue = 1 | pages = e202–8 | title = Child care problems and employment among families with preschool-aged children with autism in the United States | doi = 10.1542/peds.2007-3037 | pmid = 18595965 | url = http://pediatrics.aappublications.org/cgi/content/full/122/1/e202 }}

If these citations were altered to say "2008" rather than "2008a" and "2008b", the resulting page would not work, because the two different citations would both attempt to use the ID "<code>CITEREFMontesHalterman2008</code>". To avoid this problem, distinguish the citations by appending suffixes to the years, ''e.g.'', "{{para|year|2008a}}" and "{{para|year|2008b}}", as was done above. Any Harvard references to these citations should use years with the same suffixes.

It is good practice to verify that a page does not contain duplicate IDs by using the [[W3C Markup Validation Service]]; see ''[[#External links|External links]]''.

==Dates==
{{Reflist|group="n"|refs=<ref name="dates" group="n">
* The format of dates in the references of an article should use a consistent and unambiguous style. Example formats used in Wikipedia citations include:
:*''2009''
:*''2009-09-14'' (ISO standard format: YYYY-MM-DD)
:*''14 September 2009''
:*''September 14, 2009'' (with comma)
:*''2009 Sep 14''
:*''September 2009''
:*''Sept./Oct. 2009''
* As indicated above, month names are sometimes abbreviated, ''e.g.'', September to "Sept" or "Sept." or "Sep" or "Sep."
* Dates should not be linked in references.
* Please see ''[[Wikipedia:Manual of Style (dates and numbers)#Dates]]'' for more guidance about formatting dates.
